CIRCUIT-.CONNECTION FOR ELEC-TROLIERS.

SPECIFICATION forming part of Letters Patent No. 290,407, dated December 18, 1883. Application filed April 5, 1883. (No model.)

To all whom t may concern,.-

Beit known that I, HENRY EDMUNDs, J r., of the city,'county, and State of New York,

have invented an Improvement in Oircuit-,

Connections for Electroliers; and the following is declared to be a description of thesame.

This invention relates to the wiring and the forming of circuit-connections upon chandeliers, velectroliers, special fixtures, 85e., either when used upon new articles or upon what is termed adapted Work.77

' I employ a connection to the gas-pipe at the ceiling of a room, and a lhook and block or button of non-conducting material connected therewith for suspending the chandelier, and I use insulating-blocks in connection with these suspending devices, upon which the circuitconnections, circuit-fuses, or safety-switches for the electrolier are placed, and I carry through these blocks the direct wire for lighting; and in the junction-box, from which radiate the tubular arms of the chandelier, I take wires to each lamp and connect them with this direct conductor. The return-wires are brought, one from each light, through their respective switches to the distribution-box, and they are by preference grouped in pairs and led up the tubular stem of the chandelier to the safety switch-block, and here each separate wire is secured to a binding-screw and connected by a metal plate and circuit-fuse to a union-ring, from which one wire leads to a binding-screw and circuit-fuse in the ceilingblock, and so away to the line. By this construction I am enabled to insulate the chandelier completely from all metallic contact that is likely to cause a leak of current or a false circuit; and by this arrangement of circuits I can control each incandescent lamp independently from any other lamp on the electrolier, and where any circuit-fuse is melted it only affects the lamp in the branch circuit containing such fuse, and a new circuit-fuse can be put in without disturbing any of the wiring.

In the drawings, Figure l is an elevation of a two-light electrolier. Fig. 2 is a section of the ceiling-block, suspending-bail, and'insulating-roller, and an elevation and partial section of the suspending-block. Fig. 3 is an elevation ofthe ceiling-block` and cross-section of the suspending-block. Fig. iis aplan of the suspending-block, and Fig. 5 is a section of the distribution-box at the junction of Athe tubular arms of the electrolier.

The electrolier B may be of any desired construction or ornamentation, and have anydesired number of incandescentlamps, A, my system of circuit-connections being equally adapted to all.

The electrolier is suspended from the gaspipe in the ceiling as follows: A coupling, a', having projecting lugs c2, is screwed on the gas-pipe a3, 'secured in the ceiling. Passing through these lugs a2 is an axis or pin, b2, carrying the insulating-roller b3, which is, by preference, made of porcelain, although other similar material will answer equally well. A bail, c', is suspended from this roller, its ends passing through the fuse-block D, and through a metal -ring held by nuts c2. In the top of this block D is a thimble, d, secured by screws to said block, and into this'thimble the tubular stem e of the electrolier is screwed, as seen in Fig. 3. The head-block C andfusc-block D each have an eXtra case of plain or ornamental sheet metal corresponding in appearance with the electrolier, and the same can be removed to give access to the circuit-connections. i

lllhe distribution-box E is, by preference, a circular cup-shaped casting, into the upper, part of which the tubular stein e of electrolier is screwed, and into the sides of which the tubular branches e are screwed. Its lower side is open, and a plate, f, with a spindle f. is screwed to the same, and this spindle has screwed upon it the ornamental end g of the electrolier.

The circuit-connections are made as follows: There is a recess in the ceiling-block C at C', and this contains a plate of metal, g', and binding-screws 5 6, and the main or direct circuitwire b comes lfrom the ceiling through a hole in the block C to the binding-screw 5, the current passing through the Wire b to said screw 5 and to plate g', from thence to binding-screw G, and vby a second wire, b, to binding-screw 8, plate g2, andbinding-screw 9. These bindingscrews 8 and 9 and plate g2 are upon the top' IOO ofthe fuse-block D. From binding-screw 9 the circuit-Wire 4 descends through the tubular stem e ofthe electrolier to the distributionboX E. At this point independent direct circuit-Wires leading to each incandescent lamp are connected to the circuit-Wire 4t, thus coinpleting the positive connection to the lamps. rlhe return-wires 2 from the incandescent lamps A are carried through the switch I-I, through the tubular branches c t0 the distribution-box E, and there I prefer to connect them in pairs, and so conduct themup the chandelier or electrolier and to the outside of the fuse-block D through the holes h. Upon the fuse-block D each of the Wires 2 is connected to a binding-screw, 7, and electrode or plate o; and Figs. 2, 3, 4, and 5 are represented as wired for and belonging to an electrolier having six incandescent electric lights, the plan View, Fig. 4, being hexagonal, but the number may vary. Around the block D is an electrical union-ring,77 n', and each circuit-Wire, 2, is electrically connected with it through the binding-screws 7, electrodes or plates c, and circuit-fuses t, thus putting an independent safety-switch or circuit-fuse in the branch electric circuit of each incandescent lamp. From this union-ring n the Wire l1 passes from the binding-screw 12 up into a recess, c", in the ceiling-block C, and is connected Wit-l1 the binding-screw 17, and from this binding-screw 17 the electric current passes to the electrode or plate el, circuit-fuse t?, electrode or plate o, binding-screw 17, (see Fig. 3,) and so away to the return-line wire.

The great advantage of connecting the circuit-Wires and using circuit-fuses in each branch circuit is that the burning out of one fuse only affects one lamp, and the connections being upon,the surface of blocks, as set forth, are easily got at to replace the i'uses and also to adjust the Wires, if required.

These improvements in circuit-connections for electroliers are especially useful in what is known as adapted iittings7 where gasolicrs or chandeliers are formed into electroliers, retaining the ixtures as a Whole, but adapting them for electrical lamps.

I remark that the fuse-block D is to be furnished with as many circuit fuses and connections from the return-Wires 2 as there are incandescent lamps upon the electrolier.

I claim as my invention- 1. The combination, in an' electrolier, ofthe ceiling-block C, bail c', for suspending the electrolier, the fuse-block D, at the upper part of the tube e, the distribution-box E, at the junction of the tube e and branches, and incandescentlampsA,andcircuit-wirespassing through the pipes, substantially as and for the purposes set forth.

2. The combination, with an electrolier, of the pipe a, a coupling-tube, a, screwed upon the pipe a, projecting lugs a2, axis b2, insulating-roller b, bail c', block D, through which the bail passes, and the nuts c2, for suspending the electrolier, substantially as and for the purposes set forth.

3. In an electrolier, the combination, with the ceiling-block C, having openings C C2, of the plate g and binding-screws 5 6,Within such openings, and forming connections for the direct-circuit wire, and the binding-screws 7, electrodes or plates n c, and circuit-fuse t in such ceiling-block, and forming the circuitconnections for the return-circuit wire 2, substantially as set forth.

4. In an electrolier, the combination, with the fuse-block D, its bail c', and the plate d, to which the tubular stem c of the electrolier is secured, of the binding-screws 7, electrodes or plates o, circuit-fuses t, union-ring o', and binding-screw 12, around the fuse-block and forming the circuit-connections for the branch circuit-Wires, and the binding-screws 8 and 9, and plate g2, upon said block D, for forming the circuit-connections to the direct circuitwires, substantially as set forth.

An electrolier having tubular stem and branches with circuit Wires and lamps, in combination with a suspending-bail and insulating roller or support for such bail, substantially as set forth.
